Specifications

Product Data
Applications	ELISA, IF, IHC, WB
Recommend Dilution	Peptide ELISA: 1/16000 (Detection Limit). Western Blot: 0.03-0.1 µg/ml. Approx 37kDa band observed in Human Liver, Testis and Tonsil, and in Mouse Liver and Rat Heart lysates, and in cell lysates of HeLa and NIH3T3 (calculated MW of 36.1kDa according to Human NP_002037.2, Mouse NP_032110.1, and Rat NP_058704.1). Primary incubation 1 hour at room temperature. Immunofluorescence: 5 µg/ml. Strong expression of the protein seen in the cytoplasm of HeLa cells.  Immunohistochemistry on Paraffin Sections: 2 µg/ml. In paraffin embedded Liver shows textured cytoplasm staining in hepatocytes.
Reactivity	Canine, Human, Mouse, Rat
Host	Goat
Clonality	Polyclonal
Immunogen	Peptide with sequence from the internal region of the protein sequence according to NP_002037.2.
Specificity	This antibody is specific to GAPDH (Internal).  This antibody is expected to recognize both reported isoforms (NP_002037.2; NP_001243728.1). Reported variants represent identical protein: NP_001276674.1, NP_002037.2, NP_001276675.1.  GAPDH is constitutively expressed in almost all tissues at high levels. It is therefore a useful marker when a Loading/Positive Control is required in Western blotting.
Formulation	Tris saline, pH~7.3 State: Aff - Purified State: Liquid purified Ig fraction Stabilizer: 0.5% BSA Preservative: 0.02% Sodium Azide
Concentration	lot specific
Purification	Ammonium Sulphate Precipitation followed by antigen Affinity Chromatography using the immunizing peptide
Conjugation	Unconjugated
Storage Condition	Store undiluted at 2-8°C for one month or (in aliquots) at -20°C for longer. Avoid repeated freezing and thawing.
Predicted Protein Size	36.1 kDa
Gene Name	glyceraldehyde-3-phosphate dehydrogenase
Database Link	Entrez Gene 2597 Human UniProt ID P04406
Background	Glyceraldehyde 3-phosphate dehydrogenase (GAPDH) is a metabolic enzyme originally thought to be only involved in Glycolysis. GAPDH is constitutively expressed at high levels in almost all tissues and serves therefore as a useful marker for the measurement of equal loading in western blotting experiments. Because of its ubiquitous expression, GAPDH is often seen as a housekeeping gene. However in the last two decades, every year a new function for this enzyme has been revealed. Besides its central role as a cytoplasmic enzyme in Glycolysis, recent evidence suggests that mammalian GAPDH is also involved in a great number of intracellular processes such as DNA replication and repair, nuclear membrane fusion, endocytosis, nuclear translocation in apoptosis, microtubule bundling, vesicular secretory transport, maintenance of telomere structure, phosphotransferase activity and nuclear RNA export. We now know that GAPDH is not only in the cytoplasm, but it shuttles between the cytoplasm and the nucleus and membranes. A lot of reports demonstrate the role of GAPDH in different pathologies such as progression in prostate cancer and ovarian cancer (mRNA stability), programmed neuronal cell death, and agerelated neuronal diseases. For example the sub-cellular distribution of GAPDH is abnormal in patients with Alzheimer's disease.
Synonyms	GAPD, CDABP0047
